DESCRIPTION
The ST93CS66 and ST93CS67 are 4K bit Electri-
cally Erasable Programmable Memory (EEPROM)
fabricated with SGS-THOMSON’s High Endurance
Single Polysilicon CMOS technology. The memory
is accessed through a serial input D and output Q.
The 4K bit memory is organized as 256 x 16 bit
words.The memory is accessed by a set of instruc-
tions which include Read, Write, Page Write, Write
All and instructions used to set the memory protec-
tion. A Read instruction loads the address of the
first word to be read into an internal address
pointer.
